The commander of an interceptor battalion in Ukraine’s 3rd Army Corps said his unit destroyed several thousand Russian aerial targets during Operation Vivaldi, ArmyInform, the Defense Ministry’s news agency, reported on 21 October.

Operation Vivaldi is a Ukrainian counteroffensive north of Lyman in Donetsk Oblast, where the 3rd Army Corps has reported liberating settlements. In its third phase, Ukrainian forces reclaimed five settlements and expanded their gains to 176 square kilometers. Strikes on Russian logistics and electronic warfare likely neutralized Russia’s drone defenses before Ukraine sent in armor, the Institute for the Study of War assessed.

The commander, who uses the callsign “Betsyk,” leads the interceptor battalion of the 1030th Anti-Aircraft Missile-Artillery Regiment “Aquila,” part of the 3rd Army Corps. He said Russian forces deployed large numbers of reconnaissance drones to locate Ukrainian positions after the corps began advancing.

Betsyk named Zala, Orlan, Supercam, Merlin, and Knyaz Veshchiy Oleg among the reconnaissance drones used by Russian forces.

Russia also brought in reinforcements and units operating strike drones, including first-person-view (FPV) quadcopters, Molniya fixed-wing FPV drones, and Lancet crews, he said. At one stage, Russian forces deployed crews from their Rubicon drone unit to disrupt the advance, but the move did not change the situation.

Betsyk said his battalion’s work deprived Russian forces of the ability to strike Ukrainian troops and track their movements.

Jet-powered Shaheds: speed is the main challenge

The regiment also works against Russian strike drones heading for targets behind the front line. Betsyk said interceptor crews had destroyed some jet-powered drones, but not in significant numbers.

The main difficulty is speed, he said. Interceptor drones need to reach 500–600 km/h to intercept Russian jet-powered attack drones, according to Betsyk.

For now, the regiment mainly uses conventional air-defense systems against these targets: self-propelled anti-aircraft systems, surface-to-air missile systems, and portable surface-to-air missile systems. Betsyk said these systems were historically designed to engage jet-powered targets.

He compared the current challenge with the early use of piston-powered Shaheds. Those drones initially posed a serious threat but later became easier for Ukrainian air defenses to counter. Russia has largely stopped using piston-powered Shaheds on most fronts since summer, he said, but continues to use piston-powered Gerbera drones, which are relatively cheap and can partly exhaust Ukrainian air defenses. The main drones Russian forces use now are jet-powered Shaheds, he said.

Betsyk expects Russian forces to adapt if Ukraine fields effective interceptors against jet-powered drones. They will seek ways to evade the interceptors, increase speed, improve navigation, and change their tactics, he said. However, he added that the battalion had not observed a major evolution so far and did not expect the drones’ speed to double.

What the corps says Vivaldi achieved

Separately, 3rd Army Corps commander Andrii Biletskyi said Ukrainian forces retook 277 square kilometers and 16 settlements during Operation Vivaldi, Ukrainska Pravda reported. Biletskyi also said Russian losses exceeded 8,000 personnel, according to ArmyInform. These figures are Ukrainian claims and have not been independently verified.

Elon Musk ordered the speed cap on Starshield, the military version of SpaceX’s Starlink network that Ukraine’s drones rely on, The Wall Street Journal reported on 20 October. Earlier, Musk said that such limits are decided by the US military and “ultimately POTUS.” Speaking to reporters in Eau Claire, Wisconsin, on 20 October, according to WSJ, US Defense Secretary Pete Hegseth said, “We haven’t made any directives or anything like that,” CBS News reported.

For a week, no one with a hand on the system said the decision was theirs. Musk pointed to the US military and the president, and Trump said he did not know who it was. Meanwhile, Ukrainian officials said the cap has hampered the drones they use to intercept Russian Shaheds and to strike Russian forces in occupied territory. Kyiv says the cap remains in place, and at about 160 km/h it makes intercepting jet-powered drones and missiles that fly about twice as fast virtually impossible.

Musk spoke with administration officials, including Trump, before the cap, a source says

Musk capped the speeds at which Ukrainian hardware could stay connected to the network, people familiar with the matter told WSJ. The slowdown, which began on 14 October, left some of Ukraine’s strike and interceptor drones virtually useless, WSJ said.

WSJ’s sources differ on Trump’s role. Some US officials said Musk acted on his own and that Trump did not specifically order any retribution against Ukraine. One person said Musk spoke with several senior administration officials, Trump among them, before imposing the cap. Two people said Musk and Trump discussed the decision by phone soon after the slowdown became public.

During the uproar, SpaceX representatives called White House counterparts. They asked for a shared message that the company and the administration had coordinated before Musk’s directive, the people said. The White House ran an informal inquiry into who ordered the slowdown, WSJ said.

Musk held several conversations with administration officials before the order to understand the president’s thinking, CBS reported, citing sources. He dislikes his company being seen as profiting from the war, and it is unclear how his order was carried out, CBS said.

Hegseth points to Starlink’s terms of service

Hegseth said the US had not pulled anything back. He said Starlink “has the option” to make decisions under its terms of service, and that from the Pentagon’s view nothing had changed, CBS reported.

Speaking to reporters as he left the White House on 16 October, Trump said he did not think either he or Musk was responsible, The Telegraph reported. On 19 October, he said, “I don’t know who it was, but I’d like to find out.”

Last week, a bipartisan group of senators asked the Pentagon’s inspector general to investigate whether officials “directed” or “authorized” changes to Starlink and Starshield services and intelligence sharing affecting Ukraine.

Earlier reports pointed at the White House

On 15 October, Reuters reported that the order came from inside the White House. The officials said Pentagon leaders received a message that the Starshield service for Ukraine’s military needed to be slowed, but did not say who made the decision or who carried it out. A senior US official said “No such request was ever made by the president.”

On 16 October, The Telegraph reported, citing four sources, that Musk approached Trump with the idea of the speed limits. One of the sources said Trump agreed.

Analysts and Kyiv say the cap is still in place

Michael Kofman, a war analyst at the Carnegie Endowment, said, according to WSJ, that Ukrainian strike and interceptor drones remain limited to 160 km/h. He said actual connections run below 130 km/h, which still hampers strikes and air defense.

On 20 October, Ukraine’s top diplomat in Washington, Denys Sienik, said Kyiv was still waiting for answers from the Pentagon and SpaceX, WSJ reported.
